The Security Guard duty monitor below, shown in eight circuits at Digital Circuits – 1 are examples of logic circuits, i have converted them from the DOS Orcad to Orcad 9 and corrected some errors a few years back.

These circuits can be used for looking at the logic blocks or to learn. This product was [...]

ICL8038 Versatile Waveform Generator

delabs — Sat, 17 Nov 2007 12:29:49 +0000

ICL8038 Device Information

The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can [...]
